MCP Setup Guide

Step-by-step setup for connecting SeeLLM MCP to Claude Desktop, Cursor, and other AI assistants.

Generate an API Key

  1. Go to app.seellm.com
  2. Navigate to Settings > API Keys
  3. Click Create API Key
  4. Copy the key (starts with sk_live_)

API keys authenticate your MCP connection and scope access to your organization's data.

Claude Desktop

  1. Open Claude Desktop settings
  2. Go to Developer > Edit Config
  3. Add the SeeLLM server:
{
  "mcpServers": {
    "seellm": {
      "url": "https://mcp.seellm.ai/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_your_api_key_here"
      }
    }
  }
}
  1. Restart Claude Desktop
  2. You should see the SeeLLM tools listed when you start a new conversation

Cursor

  1. Open your project root
  2. Create .cursor/mcp.json (or edit if it exists):
{
  "mcpServers": {
    "seellm": {
      "url": "https://mcp.seellm.ai/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_your_api_key_here"
      }
    }
  }
}
  1. Restart Cursor
  2. The SeeLLM tools will be available in the AI pane

Claude Code (CLI)

  1. Create .mcp.json in your project root:
{
  "mcpServers": {
    "seellm": {
      "type": "url",
      "url": "https://mcp.seellm.ai/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_your_api_key_here"
      }
    }
  }
}
  1. Run claude — the MCP server connects automatically

Custom / OpenAI GPTs

For custom integrations, the MCP server is available at:

POST https://mcp.seellm.ai/mcp
Authorization: Bearer sk_live_your_api_key_here

The server uses the Streamable HTTP transport defined in the MCP specification.

Troubleshooting

Tools not showing up

  • Verify your API key is valid and hasn't been revoked
  • Check the MCP server URL is exactly https://mcp.seellm.ai/mcp
  • Restart your AI assistant after config changes

Authentication errors

  • API keys start with sk_live_ — make sure you're using the full key
  • The Authorization header format is Bearer sk_live_... (with the space)
  • Keys are scoped to your organization — they only access your org's data
